The victim's serum sample was subjected to ion chromatography/mass spectrometry.

A peak at 89.2 m/z, subsequently identified as oxalate, was detected at ~5X the normal (~0.16mcg/ml) serum concentration.

Urine Collected at Autopsy

A portion of the victim's urine sample was then subjected to a colorimetric oxalate test.

If oxalate is present, it reacts with oxalate oxidase in the presence of oxygen to form hydrogen peroxide and carbon dioxide. The hydrogen peroxide further reacts with two chemicals (MBTH and DMAB) to form an indamine dye that is detected at 590nm.

Oxalate concentration in the urine was determined to be 73mg/L. Calcium oxalate crystals were also apparent after microscopic examination of the urine.

Conclusion:

Both the blood and urine analysis revealed a higher than normal presence of oxalate in the system. While an abnormally high level of oxalate is present in the victim’s system, it is not at such a concentration to cause death. Oxalic acid (oxalate) is found in plants such as beets, rhubarb, and spinach. Furthermore, ethylene glycol, if ingested, is metabolized to oxalic acid (oxalate).

ATTEST

I certify that I performed the above analysis and explanation and that the above is an accurate summary of the analysis results.

Did Dale mean to poison Andrea? I guess just to make her suffer a bit, not to kill her though. Evidence suggests he knew what he was doing.
I wonder what happened to the clothing and fibers underneath fingernails that went to lab for analysis?

Yea he meant to poison her Daroo196 his brooding and jealousy got too much and your right he wanted her to suffer or maybe just quit or maybe he was planning something bigger and this was a test to see if he could get away with it?
And yea what...

And yea what happened to the fingernail analysis, the coroner's report said they went to get tested? And how could there be no fingerprints at crime scene?
